Testcase gcc.target/arm/cmse/cmse-14.c checks whether bar is called via
__gnu_cmse_nonsecure_call libcall and not via a direct call. However the
pattern is a bit surprising in that it needs to explicitely allow "by"
due to allowing anything before the 'b'.

This patch rewrites the logic to look for b as a first non-whitespace
letter followed iby anything (to match bl and conditional branches)
followed by some spaces and then bar.

Some of the tests in the gcc.target/arm/cmse directory (eg.
gcc.target/arm/cmse/mainline/bitfield-4.c) are failing when run without
an architecture specified in RUNTESTFLAGS due to them not adding the
option to select an Armv8-M architecture.

This patch fixes the issue by adding the right option from the exp file
so that no architecture fiddling is necessary in the individual tests.

Commit r253825 which introduced some sanity checks for sbitmap revealed
a bug in the conversion of cmse_nonsecure_entry_clear_before_return ()
to using bitmap structure. bitmap_and expects that the two bitmaps have
the same length, yet the code in
cmse_nonsecure_entry_clear_before_return () have different size for
to_clear_bitmap and to_clear_arg_regs_bitmap, with the assumption that
bitmap_and would behave has if the bits not allocated were in fact zero.
This commit makes sure both bitmap are equally sized.

ISO C17 won't go to ballot until December, meaning publication of the
standard won't be until 2018, leaving ambiguity as to whether people
will end up referring to the standard as C17, as it's currently known
and which corresponds to the __STDC_VERSION__ value, or C18 based on
the publication date.

In case people end up referring to this standard as C18, this patch
adds corresponding option aliases -std=c18, -std=iso9899:2018,
-std=gnu18 so people can use those names based on publication date if
they wish.  The "expected to be" explanations in help texts and the
manual can be removed as and when the standard is published, hopefully
before GCC 8 is out.

the untyped HSAIL regs.

Instead of always representing the HSAIL's untyped registers as
unsigned int, the gccbrig now pre-analyzes the BRIG code and
